FRAME AND COMMAND EDITORS

This command will allocate two bytes of output data in the OUT area and no swapping will occur. The data is followed by a two-byte CRC error check field and the CRC calculation starts with the first byte in the frame (0x0000).

The same steps are required for the response frame. If the response holds data, it should be allocated in the input area that starts at address 0x002. To apply the changes, select File > Apply Changes. To exit without saving, select File > Exit.
